VEHICLE-BRAKE..

SPECIFICATION forming part of'netters patera No. r761,460', 'dated May31, 1904.

Application filed October 17, v1903; Serial `No. 177,403. (No model.)

To all whom it may concern:

Be it known that I, J oHN G. EBKEN, a citi- -zen of the United States ofAmerica, residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain newy and useful Improvements inVehicle- Brakes, of which the following is a specification.

My invention relates to an' improvement in rotary brakesl for carriages,wagons, automobiles, and the like; and it consists in having new andnovel features not used heretofore, as is shown in the drawingsanddescribed in the specification.

In the accompanying drawings, illustrating my invention, Figure 1 is avertical .section view of my -improved brake. l Fig. 2 is asectionalview taken on the line 2-2 of Fig. 1. Fig1 3 is a View, partly broken"away, showing one of the dust-proofwashers.

The object of my invention is to construct a wheel-brake-forrubberltires and one that will not destroy the tire ywhen broughtinto'. engagement with the brake. -The Hat shoebrakes now in use forsuch tires-are very destructive to the surface VAof the tires, as itcomes into contact too quick, thereby cutting into the rubber andmutilating the tread of the tire, whereas with my`brake the pressure vis exerted gradually and also allows the brakewheel to revolve, as bythis feature the gum 4is not chipped off, as is the case in the Hat`Ywheel 5. This will force the brake, as shown in Fig. 2, away from thewheel, but at the same time will force the rubber 3 against the innerface of the ring 6, as at 7, thereby retarding the movement of thewheelli. Ipro- .vide on each side of the brake-wheel 5 dustproof washers8, and in order to allow of the movement of the wheel that is requiredin braking make the opening 9 larger on two sides, as shown at 10. Thiswill permit of the backward movement ofbrake-wheel Without altering therelative -position of the brake-beam. The washers also have inturnedianges 11, that fit into corresponding grooves 12,'formed in the body ofbrake-wheel, as by this form dirt will notV so easily work into theinterior of the wheel. In order that the tire will grip the wheel-brakemore readily, Iv iiute 'the edges, as is illustrated at 13., y

I do not care to limit myself to the exact details of construction, asvarious changes may be made without departing from the spirit` Vof myinvention.

, l'What I claim, and desire to secure by Letters Patent, is-

In avehicle-brake, a brake-beam having a square shaft formed thereon, arubber body fitting into the annular recess of wheel, a ring surroundingthe rubber body, washers with inturned flanges and having the centralopening larger than the square shaft for the lateral movement of thewheel-brake, substantially as described.

In testimony whereof I aiiX my signature, in the presence of twowitnesses, this 1st day of September, 1903.

'JOHN G. yEBKEN.
